Products made of stainless steel have gradually entered industrial applications because of their long service life, not easy to rust, and green environmental protection. Stainless steel pipeline pumps are among the best. The stainless steel pipeline pump included in the stainless steel pipeline pump has been widely used in the market in recent years, and is loved by the majority of users because of its corrosion resistance, long service life, light weight, safety and hygiene. Moreover, the cost of construction is comparable to that of ordinary sewage pumps, because the price of its brown metal has continued to increase over the years, and the price is almost the same. The used stainless steel material is a green and environmentally friendly material, which can be recycled 100%, so in recent years, it has become a leader in stainless steel high temperature and corrosion resistant submersible pumps. Especially in recent years, countries in the food industry have put forward higher requirements. Stainless steel materials have gradually entered the stage of history because of their safety and hygiene. For rigid requirements, stainless steel pump products represented by stainless steel submersible pumps have begun to shine in food products. With the sharp increase in the market, the stainless steel pipeline pump industry is facing new technological innovations. Various companies are also competing to launch their own killers, constantly improve their R&D teams, and study related core production technologies, so as to improve their competitiveness in the market. Pump products represented by stainless steel pipeline pumps are leading the entire pump industry to move forward, and the raw material market driven by this, new stainless steel materials continue to come out. Various patented technologies and the continuous improvement of specifications are constantly driving the entire industry chain to a higher and more orderly goal. At the same time, it is also expected that pump products led by stainless steel sewage pumps will go abroad and become more popular in the world. Play the pride of Made in China on the big stage. Vacuum Units in Short Path Distillation Applications of Importance 2BE3 Series Liquid Ring Vacuum Pump

The performance curve of vacuum pump unit is used to express the conversion characteristics of water flow energy under different working conditions, which is the external manifestation of the internal flow law of the pump. Like ordinary centrifugal pump, the constant speed characteristic curve of engine cooling water pump of vacuum pump unit is the relationship curve of flow and head, flow and efficiency, and flow and power at a certain speed, As shown in Figure 3a, it can directly describe the operation performance of the engine cooling water pump at constant speed. However, because the speed of the engine cooling water pump is constantly changing when it works, the variable speed characteristic curve of the pump must be given, as shown in Figure 3B. The variable speed characteristic curve of the engine cooling water pump mainly maps the flow, head and power curves corresponding to different speeds, In order to reflect the comprehensive performance of engine cooling water pump more intuitively, it is necessary to draw the two performance curves on the same graph to show the performance parameters, which increases the hydraulic loss and reduces the efficiency. At the same time, the cavitation phenomenon of engine cooling water pump is more likely to occur under high temperature, high speed and large flow conditions. At the same time, the flow in the top clearance of the semi open impeller causes the main flow to collapse and the flow velocity in the impeller passage to increase, which worsens the cavitation characteristics of the impeller and seriously affects the normal operation of the cooling system, The special working environment and matching condition decide that the design of engine cooling water pump is different from ordinary centrifugal pump. As the "heart" of cooling system, engine cooling water pump works in harsh environment with extremely limited space, The working life of the pump should be equal to or more than that of the engine overhaul period. Therefore, the reliability requirements of the engine cooling water pump and its components, such as water seal, bearing, pump shaft and impeller, are very high, so it is necessary to realize the same service life of the pump. However, due to the compact assembly structure, the shaft bearing is widely used in the engine cooling water pump to replace the common shaft and bearing combination in the centrifugal pump, The axial force produced by cooling fan and pump impeller will also change with the constant change of rotating speed. The clearance between pump shaft and support will increase noise and vibration, which will have an adverse impact on the operation performance and water seal work of the pump.
